Comparing the crown and root metric properties of double-rooted and single-rooted mandibular canine teeth.
Article in Oral radiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo compare the crown and root metric properties of two- and single-rooted/multi-canal mandibular canines (MnCn) with single-rooted/single-canal MnCn.
methodsCone-beam computed tomography images of 1000 patients (500 women and 500 men) with both right and left MnCn were analyzed. First, the root and canal morphologies of all teeth were examined. Then, the teeth were divided into three groups; (a) 2-rooted, (b) 1-rooted and multi-canals, (c) 1-rooted and single-canal. Crown lengths/sizes and tooth lengths were compared between the three groups. Statistical analyses were performed using Chi-square, one-way ANOVA, Welch, post hoc pairwise comparison, and independent sample t-tests. The significance level was set at 5%.
resultsOf all the teeth, 2.35% were 2-rooted, and 6.3% were 1-rooted/multi-canal. The frequency of double roots was higher in women (p < 0.05). Double-rooted teeth had longer crown lengths but shorter tooth lengths than single-rooted teeth (p < 0.05). In 2-rooted teeth, buccal and lingual root lengths were similar, root bifurcation levels were mostly at the mid-root, and the mean distance of the bifurcation points of the canals to the cemento-enamel junction was 4.09 mm. Double-rooted teeth were mostly observed unilaterally.
conclusionsSince 2-rooted MnCn do not differ significantly from other teeth in terms of crown sizes, it is not possible to differentiate between single- vs. double-rooted MnCn based on clinical examination.
